Cat5e (Category 5 enhanced)
- Max. Speed Up to 1 Gbps
- Available in Shielded and Unshielded varieties.

In , Category 5 cable was introduced. It provided 100 Mbps network speeds with 100 MHz bandwidth and could send network data packets up to 100 meters (328 feet) without amplification. The cable's capabilities were a big leap forward, but they pale in comparison to what came next: Cat5e, or enhanced Category 5, cables. This improved version of Cat5 cabling was able to push the data transfer rate to 1 Gbps — ten times the previous rate. Even though this type of cable is more than 20 years old by now, it is still very popular and widely used. Newer standards have emerged since then, with Cat6, Cat6a and Cat8 being officially recognized by the Telecommunications Industry Association (TIA), with Cat7 still waiting to receive the TIA's blessing.

Cat6 (Category 6)
- Max. speed up to 10 Gbps @ 55 m (164 ft.)
- Available in Shielded and Unshielded varieties.

Category 6 supports data transfer speeds up to 10 Gbps at 250 MHz along with improved crosstalk protection. The standard only supports the 10 Gbps speed up to 55 meters (164 feet), so if you need higher bandwidth in your network, Cat6 is the entry-level choice. Both Cat5e and Cat6 begin to become part of the bottleneck in your network as we see continuously faster Internet connections in both the home and office environment.

Cat6a (Augmented Category 6)
- Max. speed up to 10 Gbps @ 100 m (328 ft.)
- Available in Shielded and Unshielded varieties.
If your requirement is a 1- to 10-Gigabit Ethernet network, Cat6a is still currently the right choice for most circumstances. Cat6a supports the same 10 Gbps transmission speed as Cat6, but up to 100 meters (328 feet) and at 500 MHz. The cable also further reduces crosstalk.

Cat7 (Category 7)
- Max. Speed Up to 10 Gbps
- Only Shielded
- Best to be avoided

Category 7 was ratified as a standard in as per the ISO/IEC , but still is not recognized by EIA or TIA. Cat7 never superseded Cat6a since neither of the governing bodies approved the standard. As such, you will see many different claims from suppliers. Further confusion and uncertainty arose when two companies developed their own patented designs for new connectors (TERA developed by The Siemon Company; GG45 developed by Nexans). If you use Cat7 cable with Cat6a modular plugs, you will have better performance. Realistically, Cat6a is your better choice as it is a supported official standard, and you can be assured of quality and data integrity. Cat7 supports the same transmission speed and distance as Cat6a — 10 Gbps up to 100 meters (328 feet) — but at 600 MHz with even less crosstalk.

Cat8.x (Category 8, 8.1 [Class I]and 8.2 [Class II])
- Max. Speed Up to 40 Gbps- Only Shielded

Cat8 is recommended for data-center environments or high-speed switch-to-switch and server communications in a 25 Gbps or 40 Gbps copper network. Cat8 is the best choice unless you want to install a fiber network, too. Due to the design, Cat8, Cat8.1 and Cat8.2 support transmission speeds of 10 Gbps up to 100 meters (328 feet) or 25 Gbps and 40 Gbps up to 30 meters (98.5 feet) with an impressive 2,000 MHz frequency that even better prevents crosstalk. Where Cat8 and 8.1 are backward compatible, Cat8.2 is not since it does not use standard RJ45 connectors.

In modern network infrastructure, selecting the right fiber connectors is essential for maintaining high-speed and reliable communication. With various connector types available, finding the ideal option can be challenging. This article explores the most common fiber optic connectors, offering insights to help you make informed decisions that enhance your network's performance. By understanding different applications and choosing the appropriate products, you can adopt best practices for using these connectors, ensuring optimal efficiency and reliability in your fiber optic network.

Fiber optic connectors are components used to connect and disconnect fiber optic cables, playing a key role in signal transmission between fiber cables. They can accurately transmit optical signals in fiber optic lines from one fiber cable to another without introducing excessive losses. Fiber optic connectors come in various types, such as LC/SC/MTP®/MPO/ST, each designed for specific applications and performance requirements in optical communication systems. Each connector type offers unique advantages, catering to different network configurations and ensuring efficient and reliable optical signal transmission.

For instance, LC connectors, commonly used in high-density environments, include components like dust caps, ferrules, connector bodies, and boots. Each part plays a vital role in maintaining signal integrity and preventing damage, such as the dust cap protecting the ferrule from contaminants, and the boot preventing bending stress on the fiber cable. By understanding these components and their applications, you can make informed decisions that optimize your fiber optic network's performance.

What Fiber Optic Connectors Are Used For

Fiber optic connectors have a variety of uses, depending on the type of connector. For example, fiber optic connectors can be used in the following areas:

Network Applications: LAN/WAN/FTTx

Fiber optic connectors are integral to a wide range of network applications, including Local Area Networks (LAN), Wide Area Networks (WAN), and Fiber to the x (FTTx) installations. In LAN and WAN environments, fiber connectors like LC, SC, and MPO/MTP® play a crucial role in ensuring high-speed and reliable data transmission across vast distances. For FTTx deployments, connectors facilitate seamless connections from central offices to end-users, supporting high-bandwidth services and reducing signal loss. Their precision and compatibility are essential for the stable and efficient operation of these networks.

In scenarios where fiber optic cables need to be terminated directly into network devices such as switches, routers, and transceivers, fiber optic connectors are indispensable. SC and LC connectors are commonly used for this purpose due to their ease of use and high reliability. The connectors provide a stable interface between the fiber cable and the equipment, ensuring minimal signal loss and optimal performance. Proper termination is critical to maintaining the integrity of the data transmitted through the fiber optic network, especially in high-speed and high-performance environments.
